Настроить канал 5 ГГц для беспроводной точки доступа с hostapd в 16.04 LTS?

Я хочу создать точку доступа WiFi с Ubuntu 16.04.6 LTS, hostapd и этой картой PCIe WiFi, которая поддерживает 802.11a / b / g / n:

Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)

Я написал следующий hostapd.conf

#the interface used by the AP
interface=wlan_local

# "a" simply means 5GHz
hw_mode=a

# the channel to use, 0 means the AP will search for the channel with the least interferences (ACS)
channel=40
ieee80211d=1
country_code=FR
ieee80211n=1

# 802.11ac support
ieee80211ac=1
wmm_enabled=1

ssid=MYSSID
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_passphrase=MYPASSWORD

Я пробовал использовать разные каналы от 0 до 40, но все равно при запуске службы hostapd появляется следующее сообщение

hostapd[1937]: wlan_local: IEEE 802.11 Configured channel (40) not found from the channel list of current mode (2) IEEE 802.11a
hostapd[1937]: wlan_local: IEEE 802.11 Hardware does not support configured channel

. У вас есть идеи? Спасибо
